Application filed December 11, 1912. Serial No. 736,226.

To allwlzom it may concern:

Be it known that I, PIERRE J. PA on'r, a citizen of the United States of America, residing at Jeannette, in the county of West'- moreland and State of Pennsylvania,'have invented certain new and useful Improvements in Glass-Furnaces, of which the following is a specification.

This invention relates to glass furnaces of the regenerative type, and has for its object to provide a furnace of such class with a gathering chamber common to and coinmunicating with a series of independent glass collecting pots from which the batches ing in time-and expense, as well as an inv of glass are removed, such arrangement enabling a number of operators to gather simultaneously a series of batches of glass from the pots, whereby a considerable savcrease in output is obtained over the form of glass melting furnace now in general use.

A further object of the invention is to provide a glass furnace with a series of independent pots, from each of which is adapted to be removed a batch of glass, and furthermoreto provide the furnace with means communicating with the pot ducts for carrying oh the gases and fumes so that these latter will not interfere with the operators when removing the batches of glass from the pots. I

A further object of the invention is to provide a glass furnace with novel means for heating the molten glass as it travels from the melting chamber to the pots so that when the glass is gathered from the pots it will be of proper consistency.

A further object of the invention is to provide a glass furnace of the class referred to which shall be comparatively simple in its construction and arrangement, conveniently operated, efficient in its use, and

strong and durable in its structure, which .will allow for the simultaneous removal of a plurality of batches of glass, and'shall be comparatively inexpensive to set up.

Vith the foregoing and other objects in view, the invention 'consistsof the novel construction, comb nation and arrangement of parts as hereinafter more specifically described and illustrated 'in the accompanying drawings, wherein is shown the preferred embodiment of the invention, but it 15 to be understood that changes, Variat ons and modifications can be resorted to which come Within the scope of the claims hereunto appended.

In the drawings, Figure 1 is a sectional plan of a glass melting furnace constructed in accordance with this invention and with the melting chamber broken away, Fig. 2 is a section on line Y-Y, Fig. 1, illustrating a portion in section of the gathering chamber, Fig. is a section on line X-X, Fig. 1. Fig. 4 1s a transverse sectional view, taken on the line Z-Z, Fig. 8, of one of the pots, also showing the removable lid therefor, Fig. 5 is a plan of one. side of the base course of the glass collecting pots and also showing in section a portion of the wall of the melting chamber, Figs. 6 and 7 are like views of the middle courses, Fig. 8 is a-plan of the upper course, and Fig. 9 is a detail sectional viewshowing the employment of a modified form of ring which acts as a barrier to prevent the heat entering through the annular heating chamber-onto the upper gas burners 3 mounted therein and the bottom of the chamber inclines downwardly toward the gathering chamber 5 having a bottom 6, a forward wall 7 andside walls 8, 9. The forward wall 7 is semi-circular in contour, and the walls 8, 9 form a continuation of the walls 1, 2 while the inclined bottom- 6 forms a continuation of. the-botto1n of the chamber 4. Arranged at the inner end of the melting chamber l is a-pair "of skimming frames 10and 11, the

function of which is to hold back any solid v matter that is floating upon the molten glass in its passage from the melting chamber toward the gathering chamber. The top 12 of. the gathering chamber is domeshaped in'contour and provided with a depending extension 13 which is seated upon the walls 7, 8 and 9 of the gathering cham ber The upper portion of the walls 7, 8

and 9 are formed with vertically disposed openings 1a which constitute outlets for the molten glass when the latter rises above av predetermined level, the molten glass passing through the outlets 14, Fig. 6 to the collecting pots to be presently referred to.

The collecting iots, any number of wh1ch may be employed, are worked' in pairs by an operator and are disposed around the gathering chamber 5. When an operator 1s removing a batch of glass from one pot, the other pot is closed by means hereinafter referred to. The pots are mounted upon the supports 15, 16, 17, 18 and 19. The supports 18 and 19 are vertically disposed, the supports 15 and 17 spaced from each other and arranged in parallelism with respect to the gathering chamber 5, while the supports 16 extend transversely and are secured in a known manner to the supports 15 and 17, the supports 15, 16 and 17 being in the form of I-bea-ms. The glass collecting pots are constructed of a series of courses of blocks of suitable material capable of withstanding the heat of the glass, four courses being herein shown. These courses are referred to generally by the reference characters A, B, U and D. The course A being the lower or base course, the courses B and G the mid dle and the course D the top, the courses A to D conforming in contour to the shape of the gathering chamber 5.

The base course A is formed from a series of rows or blocks 15 which are spaced from each other and abut against the side and end walls of the gathering chamber 5, the spaces between the rows or blocks being indicated at 16 Fig. 5 and the outer end of each of said rows, with the exception of the two end rows are reduced, as at 17*, the end rows being indicated by 18*.

Interposed between the outer ends of the rows 15 and between each end row l8 and adjacent row 15 is a substantially circular block 19"."1

The course B which is built upon the course A consists of a series of spaced blocks or slabs 20 which are mounted upon the rows or blocks 15 of the course A, the width of the blocks or slabs being such as to be flush with the walls 21 of the openings 14, the

spaces between the blocks or slabs 20 being indicated at '22. The end blocks or slabs 20 extend upon the end rows 18 of the course A and oppose right angular extensions 23 which'project from the inner end of the walls 8 and 9. The outer end of each of the blocks 19 and spaced from the blocks 24 are segment-shaped blocks 26 having their straight faces prbvided with concave recesses 27 which oppose the -concave recesses blocks or slabs 20 is cut away to provide a 25. The blocks 26 are spaced from the blocks 24 thereby providing a assage 28 which opens into the spaces 22, tiese latter constituting conduits for the passage of the molten glass from the gathering chamber 5 to the collecting pots. I

Interposed between the blocks 26 are filler members 29, Fig. 6, which are flush with the upper faces of the bl0cks26. The blocks 24 are flush with the upper faces of the blocks or slabs 20' and the blocks 26 are flush with the blocks 24. The rows 15* form the bottoms of the conduits and the blocks 19 form the bottoms of the passages 28 and also the bottoms of the pots.

Mounted on the extensions 23 and abutting against the end blocks 26 and seated upon the outer rows 18 are closure blocks 30, Fig. 6, for the outer ends of the glass conduits.

The course u is mounted upon the course 13 and consists of pairs of spaced slabs or blocks 31, Fig. 7, which abut against the walls of the gathering chamber and are mounted upon the DIOCKS or slabs 20 and have their inner faces flush with the wal l s 21 of the openings 14. The outer endsiybf the blocks or slabs 31 are curved, and seated against said curved ends of each pair of blocks or slabs is a circular block or slab 32 33 having the wall thereof registering with the walls of the concave recesses 25 and 27.

The circular blocks 32 are mounted upon the segment-shaped blocks 24 and 26, the periphery of the blocks 24 and 26 being flush with the periphery of the block 33.

provided with a centrally-disposed opening.

Interposed between the blocks 32 and mounted upon the fillers 29 are filler members 34. The course D is mounted upon the course G and consists of a series of pairs of blocks or slabs 35, Fig 8, which are of a construction similar to the blocks or slabs 31 and are mounted on these latterand abut at their inner ends against the walls of the gathering chamber.

Mounted against the inner ends of the blocks or slabs 35 are annular members 36,

the inner diameter of each of which isgreater than the diameter of the opening 33 of the block 32, and these members 36 are mounted upon the circular blocks or slabs 32, the periphery of the members 36 being flush with the periphery of the members 32, the upper face of each member 36 being formed with-an annular boss 37.

Interpos'ed between the members 36 are filling members 38 which are mounted upon the members 34. Each set of blocks 19*, 24, 26, 32 and members 36 form a glass collecting poa'the blocks 24 and 26 in connection with'the-members 19 providing the glass inlet passages, the glass entering the pots at the bottom, and the rows 15* in connection with, the blocks or slabs 20, 31 and 35 and memes filling. members 3% and 38. prbvide the con dui-ts'fo'r conducting the glass from. the openings let to the inlet passages.

The tops of the conduitsare closed through the medium of the plates39 which.

are mounted upon. the members 38 and the blocks or slabs 35. Theplates 39 are flush with the bosses 37 and have their inner ends extending into pockets i0 formed at the.

point of junction between the walls of the gathering chamber anol'the depending por-. tion of the root 12. The plates 39 are provided with hand grips ll to enable the convenient removal of the plates when occasion so requires.

Mounted upon the roof 12 is a seriesof uprights 42, one associating with each pair of glass collecting pots and to each of the uprights 4:2 is attached a swinging arm 43.

braced by the member 444-. The outer end of the arm l3 has depending therefrom an adjustable carrier which is detachably connected to a cover plate a6. The upright l2 is so disposed that when the cover plate 45 closes one of the pots of a pair of pots,

the other pot of the pair will be opened to enable the batch of glass to be gathered therefrom. When the arm 4:3 is swung, it carries the cover as therewith to open one pot and close the other pot. By this arrangement the heat is maintained in one pot While a batch of glass is being removed from the other pot of the pair. An operator uses two pots and one of the pots is open. while the glass is gathered from the other pot and after the glass has been gathered therefrom the pot is closed by swinging the cover plate 46 upon the boss 37, and such action opens the other pot so that a batch. of glass can be gathered therefrom. Whenthe furnace is not in use, suitable means is employed for closing the open pots and which is removed when the operators proceed to remove batches of glass alternately from each pot of a pair of potsl Brace members in the form of I l-beams 4:7, 48 and ell) are employed to brace the walls of the gathering chamber and also the pot construction.

Gas supply pipes 50 are mounted. in the pot structure, each. of which is provided with a burner 51 projecting into the conduit for heating the molten glass as it travels from the gathering chamber to the collect ing pot.

Built against the pot structure and cornrnunicating wit the conduits through the medium of the openings 52 is a checker work 53 which communicates by the conduit 5% with a semi-circular common receiving chamber or linehaving projecting therefrom the conducting lines 56.; 57 and 58. which open into the stack (not shown), dampers 59 being provided for the fines. The openings 52 constitute outlets for the gases fumes from. the gathering checker work is used for preve....ting the flame from passing through the dues to the stack,

The gas supplied is utilised for melting as well as lreemn the does in a molten state is supplied to the furnace any suitable manner.

In. 9 l have a which. may be employed with the glass pot to act as a barrier to prevent the heat striking the cylinder being drawn, 50 i .dicating the ring, raised. and lowered by any suitable means as 61, and 62 indicating somewhat conventionally, the pot, the heat entering onto the surface of glass in the pot through the annular heating chamber 63. l Vhen the ring is down on top of the glass in the pot it forms a barrier to the heat, also serves to prevent the cooler glass at the sides being drawn. Pins 6 L limit the downward on ring.
